rTEo STATES PATENT AMOS SPITLER, OF MOSCOIV, IDAHO TERRITORY.

FUMIGATOR.

SPECIFICATION forming part of Letters Patent No, 387,544, dated August '7, J 888.

Application filed June 2, 1888. Serial No. 275,798. (No model.)

To all whom it may concern.-

Be it known that I, AMos SPrrLEn, of Mescow, in the county of Nez Forces and Territory of Idaho, have invented a new and Improved Animal-Exterminator, of which the following is a full, clear, and exact description.

My invention relates to an improvement in animal-exterminators, and has for its obj ect to provide a portable device of simple and durable construction specially adapted for smoking out squirrels and similar animals; and the further object of the invention is to prevent the smoke or gases coming in contact with the operator and deliver the smoke or gas directly and continuously into the animals burrow.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in both the views.

Figure 1 is a perspective view of the device,

and Fig. 2 is a central vertical and longitudinal section through the same. In carrying out the invention the table 10 is provided with spaced ports 11 and two bellows, 12 and 13, attached to the under side, one bellows being located below each of the said ports.

The two bellows 12 and 13 are attached to and manipulated by a single handle, 14, which handle projects beyond the rear end of the table parallel with a second handle, 15, constituting a portion of the said table. Upon the upper face of the table a block, 16, is secured, having preferably a detachable cap, 17, in which block a horizontal essentially U shaped port, 18, is produced, communicating at each end with the ports 11 of the table,as best shown in Fig. 2. Near the rear end of the block a vertical U shaped recess, 19, is formed, intersecting the port 18, and in the lower wall of the said port 18 one end of a flexible diaphragm, 20, is secured, which diaphragm, eX- tending a distance upward in the recess 19, constitutes a valve for each outlet of the said port 18 into the said recess. Asecond recess, 21, is produced near the forward end of the block 16, and the two recesses 19 and 21 are connected by a horizontal port, 22,thc forward end of which port is provided with a valve, 23, held normally closed by a spring, 2;, engaging the outer or forward face, as best shown in M Fig. 2.

The forward end of the block 16 is pierced by a horizontal channel, 25, aligning the port 22, which channel communicates with the recess 21..

A cylindrical fire-chamber, 26, is held in any suitable manner in the forward end of the table, projecting above and below the same, having an outwardinelination from top to bottom, the said table being protected adjacent to the firechamber by a suitable metal plate, 27. The lower end of the fire-chamber is preferably conical, but may be of other form which will admit of its ready insertion into the burrow, and the upper end of said cylinder is connected with the block 16 by a tube, 28, entering the channel 25.

As the burrows of the animals are at different incliuations,it is necessary that the table be readily adjustable. To that end legs 29, having pointed lowerends, are pivoted or hinged at each side of the said table, where hinged interlocking screw'eyes are preferably employed.

In operation the cylinderis essentially filled with sulphur and leaves or straw and the fuel ignited, the lower end of the cylinder having previously been introduced in the burrow, as shown in Fig. 1. By manipulating the bellows at the rear of the table the air is forced up through the ports 11 and 18 into the recess 19, thence through the port 22 directly into the cylinder, forcing the smoke into the burrow. The valve 23 opens to admit the outward passage of the air, but immediately after closes to prevent the smoke settling back into the bellows. The operator, being stationed at the rear, and as the air is delivered direct to the fuel, is seldom, if ever, troubled with smoke.

I desire it to be distinctly understood that I do not confine myself to the conical form ofthe fire-chamber, as the same may be polygonal or partake of other shapes. The table may also be supported by a single leg,if desired,secured to the rear of the valve-block, so that the valve may be held at any.required angle.

Having thus described my invention, what I claim as new, and desire to secure by Letters laten t, is

1. In an animaul-exterminator, the combination, with a table containing spaced ports, bellows attached beneath the ports, and a fire chamber secured in the forward end of the table, of a block containing an essentially U- shaped port connecting with the ports of the table, a forward and rear recess, the latter connecting with the Ushaped port and a second port uniting" said recesses, a valve closing the forward end of the latter port, and a tubular connection between the forward recess and ii rcehamber,substantially as shown and described.

2. in an aninial-exterininator, the combination, with the table 10,coutaining spaced ports 11, bellows 12 and 13,com1nunieating with said ports, and a forwardly-inchned fil0'Cy1llldGI,Oi a block, 16, provided with the ports 18 and 22 and recesses 19 and 21 ,a springaetnated valve,

23, closing the port 22, and a tube, 28, connect ing the recess 21 and the fire-cylinder, SllbShit11- tially as shown and described.

3. In an animal-exterminator, the combination, with the table 10, containing spaced ports 1l,bellows 12 and 13, communicating with said ports, and a f0rwardly-inclined fireeylinder having a tapering end, of a block, 16, provided with parallel ports 18 and 22,a rear vertical re cess, 19 and aforward recess, 21, a spring'actuated valve, 23, closing the forward end of the port 22, a flexible valve, 20, located in the port 18 and recess 19, and a tube, 28, connecting the forward recess and cylinder, substantially as shown and described.
